Access nested values in json using System.Text.Json

I have a JSON file returned from a system that looks like this:

{
    "value1": "Hello",
    "value2": "World",
    "result":
    {
        "stats":
        {
            "count":"1"
        }
    }
}

Getting to the values "Value1" and "Value2" is no issue. However, I cannot get to "count" - Does not appear to be in a good format.

This is my code:

class Program
{
    static void Main(string[] args)
    {
        string json1 = File.ReadAllText("test.json");
        var info = JsonSerializer.Deserialize<SnData>(json1);
        WriteLine("Value1: {0} , Value2: {1}",info.value1,info.value2);
    }
}
class SnData
{
    public string value1 {get; set;}
    public string value2 {get; set;}  
}

How to get the value "count"?

The simplest way would be to replicate the structure of your json. There are handy websites that can do this for you such as http://json2csharp.com/

class SnData
{
    public string value1 { get; set; }
    public string value2 { get; set; }
    public Result result { get; set; }
}

class Result
{
    public Stats stats { get; set; }
}

class Stats
{
    public int count { get; set; }
}

You can fetch the count with the following code:

public class SnData
{
    public string Value1 { get; set; }
    public string Value2 { get; set; }
    public Result Result { get; set; }

}
public class Result
{
    public Stats Stats { get; set; }

}

public class Stats
{
    public int Count { get; set; }
}

In the main:

 class Program
{
    static void Main(string[] args)
    {
        string json1 = File.ReadAllText("test.json");
        var info = JsonSerializer.Deserialize<SnData>(json1);
        WriteLine("Value1: {0} , Value2: {1}, Count {2}", info.Value1, info.Value2, info.Result.Stats.Count);
    }
}

The above code will simply replicate the json structure.
